WATER HEATER.

Application le. September rl`he invention relates to Water heaters having thin metal heating plates; and the object ot the improvement is to provide a heater having a removable thin metal heating plate and iin means for collecting the heat in the properly directed flue gases, ordinarily wasted.

The invention is illustrated in the accompanying drawings storming part hereof, in Which Figure l is a vertical cross-section ot the heater; and

Fig. 2, a top plate.

Similar numerals refer to similar parts throughoutJ the drawings.

The heater includes the lin plate 1 and removable thin heating plate 2, the lin plate having the shouldered flange 3 tor connection to the heating plate by bolts 4, a gasket 5 being located between the plates, and a ring 6 being located between the heating plate and the nuts 7 which cooperate with bolts 4 to tasten the parts togetherthus forming the Water heating` chamber l".

A gas burner 8 is suspended beneath the heating plate as by the brackets 9 Yfastened to the burner and to the heater.

The fin plate is provided with a plurali preferablyv concentric tins l() having staggered notches ll. The cover l2, having the depending peripheral liange l2a depending aelow the burner 8 and connected to the central chimney 123 as by cylindric neck 12b, seats upon the coplanar tops l0d oi? the lins l0, and thus provides a tortuous path about the tins tor the combustion gases'ot the llames from the burner 8 after directly heating the thin plate 2, said path being indicated on the drawing by means of arrows.

A lining 12C ot insulating material is preterably located upon the Walls of the hood or cover l2 to minimize the radiation ot heat from said cover.

lVater is ted into the heating chamber la through the inlet pipe 14 threaded to neel; 14a ot' lin plate l, and discharges from the heating ychamber through outlet pipe l5 threaded to neck 152L of the lin plate.

plan View ot the heater iin 4, 1924. Serial No. 735,812.

The water thus ted through the heatinv f n t: chamber receives heat through the thin plate 2 directly from the `flame ot' the burner 8, and receives more heat ordinarily Wasted through the fins 10 ot the plate l trom tn'e flame conibustion gases directed as above described. Thus the heater oi' the present invention permits a more eiiicient utilization ot the available heat than has ieretotore been possible.

rlhe provision ot a readily removable thin heating plate 2 itastened to the lin plate by means ot the bolts 4 and nuts 7 cooperating with ring 6 and gasket 5, renders it very con venient to replace a heating plate which has been burnt through by the continuous action ot' the iame over a long period.

Frein the above it Will be obvious that a simple heater is provided Which Will not only rapidly heat Water by passing' the gases ot combustion entirely around the heater and retarding the passage ot said gases in order that the maximum heat may be derived from them; but the heater may be easily and readily cleaned ot lime deposit Which rapidly collects Where hard Water is used. lt is only necessai-y to remove the bolts 4 in order that the ring 6 and thin plate :2 may be removed, giving access to the interior ot' the heater and to the inlet and outlet pipes, all ot which may be easily cleaned of lime deposit.

I claim A `Water heater including an upper lin plate and a lower relatively thin heating plate joined to each other and Yforming an internal Water heating chamber having av water inlet and a Water outlet, and a burner, the heating plate being in the path ot the burner flame, and the tin plate having external iins in the path ot the flame combustion gases, there be-l ing a oever contacting With the edges of the iins and having a depending peripheral flange surrounding the fin plate and a central outlet tor directing the gases about the tins.

In testimony that I claim the above', I have hereunto subscribed my name.
